To all whom it may concern: .tated through approximately ninety de- Beit known that I, SIDNEY YANKAUER, a grecs, the passage of the ilu-id is positively citizen of the United States, and a resident prevented. For rotating the valve, I proof thecity of New York, borough of Manhats vde the handle 12, Whichserves also as the 60 tan, in the county and Stateof New York, sole means for retaining the valve lug have invented a new and Improved Rotary Within the casing. Thishandle is in the orm Valve, of which the following is a full, clear, of a loop, having oppositely-disposed side and exact description. members 16 and 17, one of which is adapted This invention relates to certain improveto engage withthe outer end of the valve 65 ments in rotaryvalves, and more lpartieuplug and the other of which is adapted tol larly to the means for holding the turning engage with the valve casing m alinement 'plulg within the valve casing.` With'the axis of rotation of said plug. The

As the sole means for resiliently holding the shown, the valvecasing is provided with a plug inA position. stud 19, in alinement with the axis of the 80 Reference is to be had to the accompanyturning plug, and the side member 17 of the ing drawings, formino' a part of this specifispring handle is provided with a recess or decation, in which simi ar characters of referpression 20, adapted to receive this stud or ence indicate corres ending `parts in all the projection. The handle is of resilient mate? figures, and in whicii'- rial and so formed that the two side members 85 Figure l is a side elevation of a valve con- 16 and 17 continuously tend to press toward structed in accordance with my invention; each other, whereby the valveis rmly held Fig. 2 is a longitudinal section on the line against its seat at all times independently of 2 2 of Fig. 1 Fig. 3 is a side elevation simi-.fV the extent to which it may be worn, as the lar to Fig. 1, but showing a modied form of more the valve wears, the farther it Will be 90 spring handle; and Fig. 4 is a transverse secforced inwardly by the action of Ithe spring tion on the line '4-4 of Fig. 3. handle. The valve is not onl kept firmly In the preferred form of my valve, the ento its seat and perfectly groun -by the opentire construction includes but three parts: a ing and closing movement, but the leakage is valve casin 10, a turnin plug 11, .and a further reduced to the minimum as it can es- 95 40 spring hand e 12. The .va ve casing is procape from the casing toward only one end of vlded With a passage 13 therethrough and the plug. The smaller end of the plug does extending into one side of the casing, and innot extend through the casing, and it is tersecting the passage is a conical recess 14 therefore impossible for any Huid to escape constitutlng the valve seat.

It is only tirely through the valve casing but crosses necessary to sprin the side member 16 out the Huid passage 13. of engagement Wit the stud 18 of the valve 105 Within the valve seat, I mount my imcasing and remove the spring handle, Whereproved valve plug 11, which is conical in upon the valve plug may be readily lifted orm and provided with a assage 15 exfrom its seat.

With Any suitable means may be employed for the valve plug in one position, the passages limiting the extent of rotation of the valve n@ 15 and 13 are in alinement for the free flow of lug, but I referably provide the spring the iiuid, While when the valve plug is rohandle 12 with extensions 21 and22, extend- -be made of thinner material, as the two vmaximum extent and further rotation of the the extent ofrotation of the valve.

With t e parts in the position indicated inl claim as new and desire to secure by Letters Figs. 1 and 2, the valve will be opened to the Patent:

1 1. The combination of a valve casing'havi ing a conical chamber passing partly but not i wholly through said easing and constituting a valve seat, a conical valve plug within said may be closed.

valve plug will be prevented by thc engagement of the projection 22 with the flange 24. By rotating the valve plug through ninety degrees, the valve will be closed and the proj ection 21 will come in contact with the flange 25, as indicated in dotted lines in Fig. i 1. The member 12 thus serves not only as a l handle, but also as the sole means for holding posite to said chamber and in alinement with the valve to its seat and as a stop for limiting i the axis of the plug, said handle also serving as a means for resiliently holding said valve In Figs. 1 and 2, I have illustrated the to its conical seat. spring handle in the form of a U-shaped loop 2.

tom thereof, and a handle having engagement with the outer end of said plug and also having engagement with the casing opand outlet passages, and a U-shaped spring halves each exert a spring action, and the total spring action is more than double that roduced by a single half when used alone.

n the closed loop handle, the two side members 16a, 16, of the two halves are in direct alinement with each other, as are also the two side members 17 a, 17 a opposed thereto. Save as regards the spring handle, the valve illustrated in Figs. 3 and 4, is substantially identical with that illustrated in Figs. 1 and 2. By employing the double loop and having it extend in opposite directionsfrom the axis `of the' turning plug, the valve may be opened or closed by attaching se arate cords Witnesses: v
